I know this has been asked and replied to several times over the years but the solution provided does not seem to work for me. I have the following account bound gathering tools that I would like to upgrade to account bounds ones with gliph.
Molten Alliance Mining Pick, Consortium Harvesting Sickle, Chop-It-All Logging Axe,
I went to the Black Lion exchange specialist in Lion's Arch (the one by the trading post not the one by the vault) to try and exchange them. I unequipped the tools but it still not giving me the option to upgrade them. As a matter of fact the guy does have other versions of infinite gathering tools available for upgrading but not the ones i own. I know the ones I have should be upgradable as well but it will not list them as an option to upgrade. Any help is appreciated.
